PULVERIZER.

SPECIFICATION forming part of Letters Patent No. 585,049, dated June 1897- Application filed December 29, 1896. Serial No. 617,363. (No model-) To aZZ whom it may concern: and are pivotally connected to the brackets Be it known that I, DEE ROBERTS, a citi- F F, as will be seen upon reference to all the zen of the United States, residing at Haven, figures. in the county of Tama and State of Iowa, have Upon the upper face of the pole is secured 5 invented certain new and useful Improvea segmental rack K, and a hand-leverL,pro-

A block M is adjustably My present invention pertains to pulvermounted on the rod Q, and a link or bar N izers, the construction and advantages of connects said block M to arm L. 10 which will be hereinafter set forth, reference Each of the sections A and B is provided being had to the accompanying drawings, in with a wheel 0, adjustable in relation to the whichframe, so that the frame as a whole may run Figure 1 is a perspective view of my imon wheels, as indicated in Fig. 1, or either proved machine; Fig. 2, a front face view, side alone may be sustained by its wheel, as I 5 and Fig. 3 a similar view showing one of the indicated in Fig. 3, or both wheels may be various adjustments of which the machine is elevated and the machine allowed to rest dicapable. rectly on the plows.

The object of the invention is to construct A segmental rack P is secured to the rear the frame of the machine so that it may be member of each of the sections A and B, and 20 adjusted to several different positions to suit this rack, together with a journal-bearing Q, the nature of the surface being worked upon; forms the support for the cranked arm R, also, to bring the line of draft directly in line upon the lower end of which is mounted the with the frame orbody of the machine, and, wheel 0.

To the pole at a point approximately in line which may be adjusted vertically with rela- 50 with the clevis are pivotally connected two tion to the plow-point. links or arms J, which extend downwardly It will be noticed that each plow and its attendant colter is free to swing laterally independent of the others, and this feature is of advantage in working on uneven and stony ground.

Rearwardly-extending brackets a are attached to the arms or members E throughout their length, said brackets being provided with a vertical opening.

The plow-support comprises the curved arm I), provided with a bifurcated head designed to fit over the bracket and having Vertical openings therethrough which register with the opening in the bracket. The lower member of the bifurcated head is furnished with a set-screw c, which bears against the vertical stem (Z, form ed integral with yoke e, which carries the rolling colter f. The plow g is pivoted to the curved arm Z) and is provided with suitable openings for the insertion of the ordinary break-pins.

Stem d forms the pivot upon which the plow and colter may swing, and by loosening screw 0 the colter may be raised or lowered and then secured in its adjusted position. Under some circumstances the working edge of the colter may be desired below the plow-point-for instance, where stalks or rubbish are to be out.

In Fig. 1 the sections A and B are in horizontal alinement, but should it be desired to depress the center of the machine the operator throws lever L forward, which, acting through arm L, link N, block M, upon rod C, throws the frame into the position indicated by dotted lines, Fig. 2, or, if so desired, by drawing back the lever the central portion of the machine may be correspondingly elevated. hen in any of these positions, either wheel may be depressed or elevated to the desired extent, so that a great variety of adjustments of the frame may be secured and the machine suited to the work contemplated.

The block M best performs its functions when directly below the pivotal connection of arm L, but it maybe adjusted along rod 0 to any desired point.

Having thus described my invention, what I claim is 1. In a pnlverizer, the combination of the frame comprising two sections hinged together upon a rod or bar; a jointed arch pivotally connected to said sections upon opposite sides of the hinge; a pole; arms pivotally connected to said pole at a point in front of the arch and likewise connected to the hinged sections; and means for raising and lowering the hinged rod.

2. In a pnlverizer, the combination of the frame comprising two sections hinged together upon a rod or bar; a jointed arch pivotally connected to said sections upon opposite sides of the hinge; a pole; arms pivotally connected to said pole at a point in front of the arch and likewise connected to the hinged sections; a rack mounted upon the pole; a lever provided with a forwardly-extending arm; and alink connecting thchingerod and said extending arm.

3. In a pulverizer, the combination of the frame comprising two sections hinged together upon a rod or bar; a jointed arch pivotally connected to said sections upon opposite sides of the hinge; a pole; arms pivotally connected to said pole at a point in front of the arch, and likewise connected to the hinged sections; a rack mounted upon the pole; a lever provided with a forwardly-extending arm; an adjustable block mounted on the hinge-rod; and a link connecting said block and the forward]y-extending arm.

4. In a pulverizer, the combination of the frame comprising two sections hinged together at their adjoining edges; means for elevating and depressing said hinge-joint; a wheel connected to each of said sections; and means for independently adjusting said wheels.

5. In a pulverizer, the combination of the frame comprising two sections hinged together at their adjoining edges; and a series of independent pivoted plows mounted upon the said sections.

6. In combination with the frame and its wheel; a clearer comprising a plow U and guard V carried by an arm T, journaled upon the wheel-axle; a short arm T connected to arm T and extending upon the opposite side of the axle; an arm \V connected to said short arm T; and means for holding the arm V in its adjusted position.

7. In combination with the frame; a rearwardlyextending bracket secured thereto and provided with a vertical opening a plowpoint carried bya curved arm, said arm having a bifurcated head designed to fit over the bracket; openings in said head designed to register with the opening in the bracket; a colter carried by a yoke; a stem extending upwardly from said yoke and passing through the openings in the head and bracket; and means for securing said stem.

In witness whereof I hereunto set my hand in the presence of two witnesses.

DEE ROBERTS.
